I have 4point, benz lps, and heart sme many times in my friends setup which i am very familiar. First of all i think you cant go wrong with benz, it matches any tonearm(imid to high mass of course). It plays good in any setup, thats why i decided to buy.
The tonearms is a different issue. Imho 4point is more allrounder, but it is more polite then sme. If you value prat sme would be a good choice, but if you care refinemen and borader dynamic range t kuzma is a good choice. These are my opinions, based on my experience and my system and my friend system. Analog experience can be very different, i respect any different experience and like to hear it.
